Actually, after some testing... I'm really having a problem with my mouse and half-life based games...Sometimes, when I click, the game does not respond. Sometimes, it does but thinks that I didn't release the button...If someone have any ideas about what can be causing it, would be nice...

Well... I played with the options and I managed to solve my problem. That the option Raw Mouse Input was causing the issues. Maybe it's bugged. Should I report the problem or it is more likely that it was a particular behaviour?

Same issue here on Fuduntu (fork of Fedora) with a Razer Naga. Turning raw input off solves it, but there's no such setting in Day of Defeat, so I'm getting those responsiveness issues no matter what I do.

Same problem here. I would click once, and it would unload my entire mag. It happened a few times in Half Life 1, but was much worse in DoD Source. Turned off raw mouse input and everything is fine. Using Arch Linux, KDE, Logitech G5.

2 years later, i come across this forum having the same problem. I play on a razer Naga. I always play with raw input on off, so i have no clue how to solve this. I even went to go buy a new mouse, and was upset to realize that I'm having the same issue on a new mouse. Most of the time my clicks are working in CSGO, but there are times where the click just doesn't register, or I click once and my gun will unload an entire mag. Some pls help <3

Raw input should be enabled (on). The point of raw input is bypass your system settings (ie: acceleration) and use your "raw" mouse settings. Raw input ensures more precision.

Also, if you are using V-sync, turn it off. V-Sync causes input lag and should never be enabled, especially on FPS's.
